This is a great light weight receiver at just 1.82 grams and full range as well. The connectors are JST SH connectors making this a perfect unit for running the BlueArrow S02512 servos which have the same connector, or even most linear servos. It also has a handy bind button instead of a bund plug, which makes binding a snap.
Please note, you’ll need an external brushed or brushless ESC as this unit does not have an ESC onboard.

This receiver has JST SH connectors and is plug and play with BlueArrow servos

Wiring - As shown at the front of the receiver near the bind button

Binding Process

The image below shows the correct wire order for the servo ports. Please ensure that your wire order is the same as shown in the image below. On the right is a servo connected and on the left, the power is being supplied to the Aux port. The signal wire has been removed.

To remove the signal wire from the connector use a pin to lever up the plastic retaining tab and pull the signal wire out. This same proceedure can be used to rearrange the wires in the plug to make the correct wire order if needed.

The ESC Brushed Micro 1S3A can be used to run a brushed motor with this receiver. (Link)
